One of the primary functions of the NLRB is to determine employee representation in unions through what method?

The primary function of the National Labor Relations Board (NLRB) in determining employee representation in unions is conducted through secret-ballot elections. This method is crucial because it allows employees to express their preferences regarding union representation confidentially and without fear of coercion or retaliation. Secret-ballot elections uphold the principles of democracy in the workplace, ensuring that employees can cast their votes privately, which helps maintain the integrity of the election process.

The use of secret ballots is designed to create a level playing field for employees to make their choice freely, reflecting their true desires related to union organization and representation. This process is essential in maintaining fair labor practices and empowering workers to have a say in their workplace representation.
